Jshaf Posted December 4, 2022 Share Posted December 4, 2022 Just swapped out one of my mirror light units as it was broken and blinker wasn’t working. Swapped it with factory replacement but signal still blinking fast in that side. All other lights work. Quote Link to comment Share on other sites More sharing options...
Cknox78 Posted December 5, 2022 Share Posted December 5, 2022 Check your brake lights. If one is out it will cause a fast blinker. Quote Link to comment Share on other sites More sharing options...
NH_Bulldog Posted December 6, 2022 Share Posted December 6, 2022 The rapid blink indicates a bulb out on that side. It can also happen if you replace an incandescent bulb with an LED, or in the case of a mirror light an OEM fixture replaced with an aftermarket one. In any case, the module is not recognizing the new bulb/fixture and might need a reset. Quote Link to comment Share on other sites More sharing options...
